The developing fetus requires substantial amounts of fatty acids to support rapid cellular growth and activity. Although the fatty acid composition delivered to the fetus is largely determined by maternal circulating levels, the placenta preferentially transfers physiologically important long-chain polyunsaturated fatty acids (LC-PUFAs), particularly omega-3 (n-3) PUFAs. Maternal dietary supplementation with n-3 PUFAs during pregnancy has been shown to increase gestation length, enhance fetal growth, and reduce the risk of pregnancy complications, although the precise mechanisms governing these effects remain uncertain. Omega-3 PUFAs are involved in several physiological pathways which could account for these effects, including anti-inflammatory, pro-resolving, and anti-oxidative pathways. Recent studies have shown that maternal dietary n-3 PUFA supplementation during rat pregnancy can reduce placental oxidative damage and increase placental levels of pro-resolving mediators, effects associated with enhanced fetal and placental growth. Because several placental disorders, such as intrauterine growth restriction, preeclampsia, and gestational diabetes mellitus, are associated with heightened placental inflammation and oxidative stress, there is considerable interest in the potential for dietary n-3 PUFAs as a therapeutic intervention for these disorders. In this study, we review the impact of dietary n-3 PUFAs on placental function, with particular focus on placental inflammation, inflammatory resolution, and oxidative stress.

AbstractBackground and Aims: To assess the impact of 1 year administration of omega-3 fatty acids supplements on oxidative stress parameters and atherosclerosis progression. Material and Methods: A total of 284 patients with metabolic syndrome, aged 61±6.7 years, without clinical evidence of atherosclerosis were allocated to 2 groups, matched by sex and age: group A (140 patients) - diet according to ESC/EASD recommendations; group B (144 patients) - the same diet + capsules of fish oil (1g eicosapentanoic acid, 1g docosahexanoic acid, 0,1g a-tocopherol acetate). Body fat (BF) was measured by bioimpedance analysis. For oxidative stress evaluation we used the FormOx systems monitor on a blood drop and for progression of atherosclerosis the intima-media thickness (IMT) at common carotid artery. Patients were evaluated at baseline, after 6 months and 1 year. Results: IMT significantly decreased in group B vs group A at 1 year (p<0.0001) and was correlated with %BF (p<0.001), waist-to-hip ratio (WHR) (p=0.002), leptin (p< 0.001), adiponectin (p<0.05), leptin/adiponectin ratio (p< 0.001) and oxidative stress (p<0.001). Conclusions: One year administrations of omega-3 PUFA enriched diet reduces cardiovascular risk of metabolic syndrome patients, resulting in a significant decrease of oxidative stress and atherosclerosis progression.

The Impact

Increased muscle oxidative stress and inflammatory responses among athletes have been reported consistently. In addition, it is well known that exhaustive or unaccustomed exercise can lead to muscle fatigue, delayed-onset muscle soreness, and a decrement in performance. Omega-3 polyunsaturated fatty acids (PUFAs) have been shown to decrease the production of inflammatory eicosanoids, cytokines, and reactive oxygen species; have immunomodulatory effects; and attenuate inflammatory diseases. While a number of studies have assessed the efficacy of omega-3 PUFA supplementation on red blood cell deformability, muscle damage, inflammation, and metabolism during exercise, only a few have evaluated the impact of omega-3 PUFA supplementation on exercise performance. It has been suggested that the ingestion of EPA and DHA of approximately 1–2 g/d, at a ratio of EPA to DHA of 2:1, may be beneficial in counteracting exercise-induced inflammation and for the overall athlete health. However, the human data are inconclusive as to whether omega-3 PUFA supplementation at this dosage is effective in attenuating the inflammatory and immunomodulatory response to exercise and improving exercise performance. Thus, attempts should be made to establish an optimal omega-3 fatty-acid dosage to maximize the risk-to-reward ratio of supplementation. It should be noted that high omega-3 PUFA consumption may lead to immunosuppression and prolong bleeding time. Future studies investigating the efficacy of omega-3 PUFA supplementation in exercise-trained individuals should consider using an exercise protocol of sufficient duration and intensity to produce a more robust oxidative and inflammatory response.

Abstract We investigated the impact of increased alpha-linolenic acid (ALA) dietary levels on its plasma bioavailability and its bioconversion in n-3 long chain poly unsaturated fatty acids (LC-PUFA) during a 60-day kinetics and the oxidative stress potentially associated. Rats were submitted to a normolipidic diet providing 0, 3, 10 and 24% ALA of dietary lipids during a kinetics of 0, 15, 30 and 60 days. The lipid peroxidation and oxidative stress (nitric oxide (NO) contents and catalase (CAT), superoxide dismutase (SOD), gluthation peroxidase (GPx) activities) were studied in the liver and plasma. Data demonstrated that when the diet was deprived in n-3 PUFAs, ALA, (eicosanoic acid) EPA and docosahexaenoic acid (DHA) levels decreased in all lipid fractions of plasma and in red blood cell (RBC) lipids. However when ALA was added in the diet, its bioavailability and its bioconversion in EPA was linearly correlated with the ALA intake (R2=0.98). When the diet provided 10 to 24% ALA in dietary lipids (LA/ALA, 1.6 and 5.5 respectively), ALA and EPA were more broadly packaged in all lipid fractions (triglyceride (TG), cholesterol ester (CE) and free fatty acids (FFA)) of plasma from 15 to 30 days timeframe. However only 3% ALA in the lipid diet was sufficient to promote the maximal bioconversion of ALA in DHA in phospholipid (PL) and TG fractions. Additionally, the improvement of ALA bioconversion in EPA and DHA did not impact the oxidative stress markers wich can limit lipid peroxidation. To conclude, this study demonstrated that 10% ALA in the diet for 15-30 days is the gold diet to promote its bioavailability and its bioconversion in n-3 PUFAs in rat and allowed the greatest levels in plasma and RBCs.
